Abstract
Official abstract text for this publication.
The security and privacy of a user is enhanced by monitoring the background environment in which the user is working for changes. In an embodiment, a first or reference image is acquired using a front-facing camera of the user's computing device. A second or target image is acquired using the front-facing camera. The images are compared and an alert is generated if there is a change in background that exceeds a threshold. The change may be a person who has entered the environment and is watching the computing device screen. The alert may include reducing the visibility of information shown on the screen.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: monitoring a position of a mobile communications device having an electronic screen showing information; determining that a tilt from the position exceeds a threshold value; upon the determination, obscuring at least a portion of the information; after the step of obscuring the at least a portion of the information, determining that the tilt from the position is below the threshold value; and upon the determination that the tilt…
